Facilitation of early percutaneous coronary intervention after reteplase with or without abciximab in acute myocardial infarction
Key result
Early PCI after reperfusion is linked to a ~50% reduction in ischemic and bleeding events.
- P=0.001
- n=485
Why the study?
Early PCI has shown no benefit when performed early after thrombolysis alone, and its utility after thrombolysis combined with glycoprotein IIb/IIIa inhibition was examined.
Does early PCI after reteplase with or without abciximab improve clinical outcomes in patients with acute myocardial infarction?
Comparison
Early PCI at median 63 min after reperfusion vs no early PCI
Design
Observational study with blinded core laboratory cineangiogram review
Follow-up
30-day

Implication
May support early PCI after reperfusion in AMI; hypothesis-generating observational data requiring randomized confirmation.
Study Design
Type
Observational (n=485)
Structured PICO
Does early PCI after reteplase with or without abciximab improve clinical outcomes in patients with acute myocardial infarction?
P
Population
485 patients with acute myocardial infarction treated with reperfusion therapy, evaluated for outcomes after early PCI versus no early PCI.
E
Exposure
Early percutaneous coronary intervention (PCI) performed at a median 63 minutes after reperfusion therapy began
C
Comparator
No early PCI (n=162)
O
Outcome
30-day composite incidence of death, reinfarction, or urgent revascularization; ischemic events and bleeding complicationscomposite
Main Result
Absolute Event Rate: 15% vs 30%
p-value: p=0.001
Early PCI facilitated by abciximab and reduced-dose reteplase appears safe and effective in acute myocardial infarction, reducing ischemic and bleeding events compared to no early PCI.
Limitations
- Findings should be confirmed in a dedicated, randomized trial
- Non-randomized comparison requiring confirmation in a dedicated, randomized trial
Cite This Study
Herrmann et al. (2000) conducted an observational in Acute myocardial infarction (n=485). Early percutaneous coronary intervention (PCI) vs. No early PCI was evaluated on Ischemic events and bleeding complications (p=0.001). Early PCI after reperfusion therapy for acute myocardial infarction was associated with fewer ischemic events and bleeding complications compared to no early PCI (15% vs 30%, p=0.001).
